Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

example (b):

as shown in fig. 1 and 2, a convenient pathological microtome comprises a microtome body 1 and a blowing mechanism 2 for cleaning excessive paraffin pieces;

the blowing mechanism 2 is driven by a hand wheel 3 of the slicer body 1, and a blowing port 4 of the blowing mechanism 2 is connected to the upper part of a blade seat frame 5 of the slicer body 1 through an air pipe 15.

As shown in fig. 1, the air outlet of the air duct 15 faces the blade holder 5, so that the airflow blows off the excessive paraffin pieces on the blade holder 5. Wherein the air duct 15 can be, but is not limited to, a hose, and the air duct 15 can be, but is not limited to, fixed with the slicer body 1 by means of bonding, clamping, etc.

The working principle is as follows: when the slice is initially sliced, the hand wheel 3 is rotated, and the hand wheel 3 drives the blowing mechanism 2 to generate air flow, so that redundant paraffin slices cut off on the blade seat frame 5 are cleaned. The cleaning process is carried out synchronously with the slicing process, and the slicing process is continuous. When in subsequent formal slicing, the air blowing port 4 is only needed to be transferred to other places to avoid the air flow from influencing the slicing of formal pathological tissues.

The utility model discloses a slicer can produce the air current and clear up unnecessary paraffin section in preliminary section, need not to set up unnecessary drive arrangement, and the process of cutting into slices is continuous, and it is efficient to cut into slices.

Further, as shown in fig. 1-3, the blowing mechanism 2 includes a housing 6, a first rotating shaft 7, a driven gear 8 and an impeller 9, the impeller 9 is disposed in the housing 6 through the first rotating shaft 7, and the driven gear 8 is coaxially and fixedly connected to the outside of the first rotating shaft 7;

the outer edge of the hand wheel 3 is provided with driving teeth, and the hand wheel 3 is in transmission connection with the driven gear 8.

A transmission gear 10 is arranged between the driven gear 8 and the hand wheel 3, and the hand wheel 3 is in transmission connection with the driven gear 8 through the transmission gear 10.

The transmission gear 10 is rotatably connected with the slicer body 1 through a second rotating shaft 11, and a driving gear 12 is further fixedly arranged on the second rotating shaft 11;

a connecting ring sleeve 13 is fixedly arranged on the circular surface of the transmission gear 10, the transmission gear 10 is rotatably sleeved outside the second rotating shaft 11, and the connecting ring sleeve 13 is fixed with the second rotating shaft 11 through a bolt 14; the second rotating shaft 11 is rotatably connected with the slicer body 1 through a bearing;

the transmission gear 10 is meshed with the driving teeth, and the driving gear 12 is meshed with the driven gear 8.

The transmission gear 10 is rotatably connected with the second rotating shaft 11 through a bearing.

The hand wheel 3 and the blowing mechanism 2 are in gear transmission, and the transmission mode is simple.

The working principle is as follows: when the hand wheel 3 rotates, the transmission gear 10 is driven to rotate, the transmission gear 10 drives the second rotating shaft 11 to rotate, the driving gear 12 on the second rotating shaft 11 synchronously rotates, and the driving gear 12 drives the driven gear 8 to rotate so as to drive the impeller 9 to rotate to generate air flow.

When the slice is initially sliced, the transmission gear 10 and the second rotating shaft 11 are fixed through the bolt 14 and the connecting ring sleeve 13, the hand wheel 3 can drive the transmission gear 10 to rotate when rotating, and the transmission gear 10 drives the second rotating shaft 11 to synchronously move through the connecting ring sleeve 13 when rotating.

When the slice is formally sliced later, the bolt 14 is taken down, and the connecting ring sleeve 13, the transmission gear 10 and the second rotating shaft 11 can rotate relatively. Therefore, when the hand wheel 3 rotates, the transmission gear 10 is driven to rotate, but the connection ring sleeve 13, the transmission gear 10 and the second rotating shaft 11 can rotate relatively, so that the transmission gear 10 cannot drive the second rotating shaft 11 to rotate. Further avoid the blowing mechanism 2 to produce the air current, influence formal section.

The starting/breaking of the blowing mechanism can be controlled through a gear transmission mode, air flow is not generated during formal slicing, a blowing port does not need to be moved, and the blowing mechanism does not need to be driven during formal slicing, so that the operating force of a hand wheel during formal slicing can be reduced.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
